myTouch data connection problems in 3G only

[Vesuvio]

I've had the myTouch 3G with the 3.5mm jack for about 6 weeks or so. About 5 days ago I started getting a lot of connection errors from apps and page not found errors from the browser. It got worse for a few days until I finally called TMobile customer service. They had me reboot the phone and fixed some things in my network profile. It worked great for a few hours and the problems came back. So I called customer service again and they said to try putting my sim card in another phone, that worked fine, and then they said to try a master reset of the phone. I hesitated for a day, and found during that time if I changed the standard mobile network settings to only use 2G all the time, the data connection problems went away. If I switched back to 3G, they would come back.

So, today I tried the master reset. I had trouble getting setup again because it came back in 3G and took several tries to connect to my gmail account and setup the phone. It worked ok for a while, but I'm still having the problem.

Has anyone heard of this problem before? Does this sound like a hardware with the phone? Does anyone have any suggestions about what else I might try?

Thanks

Yes, you are not alone! I have gone through 3 handset exchanges since I got the phone in early March. I finally got TMobile to give me a different handset.

You will need to call 611 and go through all the troubleshooting bs. They won't give you a different handset until you have had 3 exchanges.

They are essentially denying there is a problem, but I've had the exact same problem as you.
