Is it theoretically possible to hack the iPhone to work for sprint? I think its a great phone, but I'd prefer a physical keyboard since I do a lot of texting and web browsing. I think its less accurate than a physical keyboard but I do love the multi-touch interface. So is it possible to work the iPhone (GSM) on a CDMA carrier? I'm sure the answer is no, but I wanted to know why. If an expert on the subject can reply with a detailed answer, that'd be great! unless the answer is simple. thanks a lot guys!

Hi man...
I'm not the expert you are asking for but can tell you one simple thing about the main diference of CDMA and GSM... as I know, the GSM networks use sim cards in the phone with the information about your carrier network,etc... the CDMA phones do not use sim card and have the info. saved on the phone itself.

hope this helps meanwhile someone more helpfull answer the question...

Yeah I don't know much either and I'd agree that its one of the big differences, but the Blackberry 8830 is marketed on Sprint.com with the following feature: "Unlocked SIM Device. Use in market carrier SIM cards while traveling abroad" To my knowledge, this is the first I've EVER heard of this. I wish I could take that SIM card and stuff it into the iPhone. Although I wouldn't be surprised if using the sprint network required no SIM card, but international use allowed the use of a SIM card with an open slot. blah,

So any experts want to shed light on the differences between GSM and CDMA (and EVDO) and why we can't hack the iPhone for Sprint, which has been unlocked for use with any GSM carrier? You can get as technical as you want, I've got the brain for it...but that doesn't mean I won't ask questions! thanks a lot guys

Cheers,

The best answer to your questing is an analogy: It is like the difference between speaking English and speaking German (just a random language selected ). GSM and CDMA are different technologies or Languages. So they may run on the same frequencies and do similar things, but are not compatible with each other.

GSM phones (AT&T, T-Mo, Vodafone, etc) use SIM cards while CDMA (Sprint, Verizon) primarily do not (some do though). Verizon is selling a BlackBerry "Curve" that is marketed as a World phone. This is the exception to most rules. It is a CDMA phone that has a seperate GSM radio (phone) inside to work on the European/Asian GSM networks.

EVDO is the high speed data portion of the CDMA network (in simle terms), while UMTS/HSDPA (also known as 3G) is the high speed data portion of the GSM network. Equally as confusing is that UMTS is technically called WCDMA or wide-band code division multiple access.

This is a little off topic for the iPhone however, considering it has GSM voice and GPRS(slow)/Edge(not as slow) data technology and there will never be any "hack" to make it work on a voice CDMA network. I do predict there will be a 3G version of the iPhone by the end of 07. Still not compatible with Sprint or Verizon, but this will give the iPhone MUCH more speed when using the cellular 3g network than the current GPRS/Edge data.

There's no reason to blame Apple for being successful..

I'll agree it's beautiful and crashes less often but virus free and crash-resistant? lol I guess marketing does work.

will get my iphone today and unlock it tonight.

I think Palm OS was the best PDA OS, lean, small, fast, functional, usable. Unfortunately they had missed the critical milestone on PDA -> PDA Phone evolution, they miss the convergence idea, and have to gave their position in the market to Micro$oft. As desperate as they were, that they have released Palm Treo using Windows Mobile as the OS

As for the sake of our own interest as customer, I really expect some competition in PDA Phone OS. Even when I think iPhone as a marketing gimmick, I still have to thank Apple for "heating up" the arena.

If only Palm could eventualy found a breakthrough and added the pressure, I as a customer, would be very glad.

Full dependability on Micro$oft product is dangerous. Since their proven personality trait is when they enter something they want to take it all. Bill Gates will never satisfied until all the money in the world is HIS.

As in PC, the next thing we will see is a Lawsuit on Monopoly Practice when they incorporate every little software into their OS core in effort to get rid of every other small software house which have given us so many better alternatives.

You already see MSN Messenger, Internet Explorer and Windows Live don't you? Can't you see the pattern?

I hope you know that ca. 20- 30% from Apple Bill Gates(privat, not microsoft) belongs

only thing I don't like is: Overpriced...Made by Apple...

cdma and gsm

---

cdma is faster the fastest hspda is back to cdma the reason for sim cards was for global acknowledgment's and greed detachable esn but cons tad bit slower hspda runs on cdma network and gsm phones will work on sprint not because of nextel just cause..

verizon settings look like this

(MID)@vzw3g.com


so the whole concept of gsm cdma being non universal is BS


Fact is verizon owns all cell sites in CA rumor has it 50 % of the US so if thats the case then why don't they use gsm cause it would make them lose that ever so popular 99.9% sla speech when the quarterly shareholders get together.

hope this helps i listed all the settings some where around networking

ciao sorry to but in

Guys any unlocking tool for iPHONE

Guys any unlocking tool for iPHONE that reallly works tnx in advance

I only see one advantage to Iphone---8GB internal storage!

If WM phones are going to compete with Iphone, they better increase the amount of internal RAM, to 8GB or more!
