IMEI and a couple more questions

---

I was just wondering if running Android on our devices change the IMEI (I'm guessing not but I just wanted to make sure). I ask this because I have no data plan on my AT&T HTC Fuze, and I don't want to be slapped with a data plan because it looks like I changed devices. I compared the IMEI in Android and Windows Mobile, and saw no difference in number, but when I plugged in my device to my computer it registered as an HTC Dream (I assume this because we are using drivers from the Dream?).
This is my first time running Android on my device, runs pretty smooth, but I'm a bit hesistant to run it again until I can verify this information. The build I tried is [prj][XDANDROID][2.2][AOSP][18.7.10]RC1 RELEASED . Runs very nicely, just as fast as Windows Mobile does natively for me.

Thanks!

Just thought of a couple more questions. I was wondering, is there anyway to switch between Windows Mobile and Android smoothly? I'm fine with launching Haret from File Explorer, but how do I get back to Windows Mobile without using my stylus to soft reset. Shutting down isn't a option, I tihnk the build I'm using has a problem with that so far (just crashes when shutting down.).

I honestly don't think you have to worry about it, I don't think Android would be able to (have access to) change that value...

From wikipedia:

Unlike the Electronic Serial Number or MEID of CDMA and other wireless networks, the IMEI is only used for identifying the device, and has no permanent or semi-permanent relation to the subscriber. Instead, the subscriber is identified by transmission of an IMSI number, which is stored on a SIM card that can (in theory) be transferred to any handset. However, many network and security features are enabled by knowing the current device being used by a subscriber.

I bolded the section I felt was important

Alright, that's what I was thinking, but I thought because there were so many rules against the discussion of how to spoof your IMEI that it might be possible that this might spoof the IMEI some how. But seeing how the IMEI is the same in Android as it is in Windows Mobile, and I haven't been hit with a "You have a smartphone here's your data plan" text message, I guess I'm safe. Thanks!

I have been told by an AT&T support engineer that they are gradually going through their database and matching up IMEI's, IMSI's, and plans to ensure that everyone has a SIM and plan that matches up with their device. I don't know if they are doing this methodically, or on a case-by-case bases as people call for support or purchase new plans/devices. But there is a chance they will discover that you have a PDA without a PDA data plan at some point.

I kept my original Cingular SIM and kept putting it into new phones for years rather than using the new SIMs that AT&T sent me with new phones. I never had an issue until the purchasing department (who manages the cell phone plans, etc for my work) disabled text messaging for everyone in the company (mine was one that was not supposed to be disabled). When I called purchasing to get it fixed, texting starting working again, but in the process all my data died. Then I called about that and ended up talking directly to an AT&T support engineer. He "couldn't enable data" for me because I had an "incompatible SIM." Never mind the fact that it had been working fine before. I guess they realized that the IMSI on my SIM was from an old device that was never compatible with data when it was purchased, (but it was not blocked from data either). I ended up having to put a newer SIM in my phone to get my data working again. I think in the end, the old SIM was using the older Cingular APN information (which still worked) rather than the newer AT&T/Cingular APN information. I think they blocked my data by disallowing my device (SIM) to connect to the older APN.

Thanks for the outlook, but I believe I'm fine. I talked to several different AT&T reps, and because I got my smartphone before Nov 6th I believe (when they first started making them mandatory) I was grandfathered in, and do not have to get a data plan, unless I upgrade to a new device, or change my device pretty much. So I'm stuck with this phone until I'm ready for a data plan. I've talked to the reps before and after the plans started coming into affect. If you've never had a data plan before, you don't have to get one on your current device, just upgrading will force you too. If you warranty, that's a gray area, I've heard you can call and let them know it's a warranty, and it should be fine they'll take it off, but I've heard stories where the reps just say they can't do anything.
