How to know if connected to GPRS/EDGE or UMTS/HSDPA

[taron]

Hi all,

Do you know a software which let met know what connection type I'm using between GPRS/EDGE and UMTS/HSDPA ?

The E icon tweak doesn't work on HTC TyTN... Thanks!

It has been posted on this forum that you do not need the tweak as the TyTN will show you the network that you are connected to. I would undo what you have done and check that you are really in UTMS coverage.

... or even try a search for other threads on this :roll:

[taron]

Really?? So what should be displayed if I'm connected to HSDPA?

[kevino]

'U' I believe. Should say in the manual.

[taron]

Ok, so this is my point.
I want to know if I'm connected to UMTS or HSDPA.
and the same beetween GPRS and EDGE.

I never saw a "E" on my screen ...

Right you are Taron.
I never saw "E" on my TyTN, though I'm sure I was under EDGE coverage.
I think TyTN just doesn't show clearly what precise kind of network you are connected too.
It just shows "G" if you are under GSM network data coverage (GPRS and EDGE).
It will show "U" if you are under 3G network (UMTS and HSDPA).
:)

what a pity, but thank you for the confirmation :)

One more question http. Do you have the voicemail icon working fine on your TyTN?
I'm on SFR, and when I have a voicemail, there is no icon neither SMS (even if my voicemail is configured to send a notification)...

Thanks,

just so you know there is a registry hack to show the E instead of G when you are on the edge network. this works seamlessly. i dont know for sure but there is probably a similar registry hack for the same thing with the UMTS/HSDPA connections.

[taron]

Thanks for the tips, but it was said that this hack doesn't work on TyTN :(

You can use HSDPA in France ?

[taron]

Yes, SFR is claiming to provide HSDPA in some regions :

I have been trying the same,but in vain.
The reg tweak working for the previous models is not working on the Hermes.

Which brings me to the following question:

Previously with ADDING this new reg key the EDGE differentiation started after rebooting the device.

So some .dll obviously checked for this key, parsed and decoded it and invoked the function in the device.

Question:

How is a (secret) reg key added to the registry parsed ?

Will we find somewhere in a .dll the string "EnableDifferGprsEdgeIcon" (or in the case of the Hermes something else) in real text ?

Can we look for such a value this way ?

Come on all experts here!
I cannot believe that nobody can detail on this here!!!

(P.S. Whenever I try to analyze the ril.dll with a hex editor it just shows zeros. Why ?)

Actually it is not that simple.
First you need a proper ROM dump, with the files intact.
Then you have to know which DLL is responsible for the feature. I don't think it's RIL, it may be device.exe or whatever is showing the taskbar.
Then you need a good decompiler like IDA, which will find the strings.
Keep in mind that all strings on the device are in Unicode so when you look at a string with a hex editor you will see something like this:
65 00 66 00 67 00 68 00
for ABCD
With IDA though you get a special window showing you the list of strings.

there could be difference between what info different operators send to phones connected to their network
so this could explain why ppl expiernce different things connectionwise

help me understand this. i usually just intall 2 cabs on my 8125 after hard reset. one is the GPRS settings for media net and the Edge icon. now that cab only changes my GPRS to icon to E. prob is it dosnt change. now if i install all the extended cab files my connection is ONLY g. that must mean that there is another cab somewhere in there that enables the switch. idk someone help
this sucks. i cant even tell if i have Edge or not.

Hi levenum,

you mean a dump of all files which can be seen in a file explorer (e.g. Resco) but cannot be read, as they are marked ROM or hidden or system, don't you ?

Well there seems to be a tool for extracting such files on buzzdev, called "WM5 Files Dumper".
Unfortunately it won't work with my TyTN as it tries to write the files on to a predefied directory on "Storage Card". Unfortunately in the German version the Storage Card location is called Speicherkarte.

I do not know if it is safe to change this temporarily to Storage Card without destroying all other links and no longer be able to access or start the programs installed on the storage card.

Maybe someone could fix that rather in the "WM5 Files Dumper" where the output directory is hard-coded.
What a painful restriction ! I can imagine that this utility would be valuable for many of us trying to find out more about their devices...

I know that most of the strings are encoded in Unicode.

The Cygnus HexEditor is able to look for Unicode strings, so this wouldn't be the problem.

well for t-mobile at least, when your on 3g you are on HSDPA, where ever there is UMTS signal there is HSDPA signal (i asked the question to t-mob cs)
