Tried to update os and lost all data service

I have a storm running on tmobile. I found a fix to always get an EDGE and did it..it worked the first time and was fine for a few months but then it stopped working so I did it again. When I did my phone stopped having any data service. There are no entries in the host routing table..Ive reregistered my device a million times and its not working. Ive been on the phone with tmobile (they are no help) I read all the post about this but nothing has fixed it. I know someone out there can help me...or at least I hope!!

This must be a Tmobile issue because I am having the same problem!
Help!

Im trying to figure out if I did this or if its just another problem on tmobiles half. I did mess with changing the os so I thought it was my fault, did you do anything to the phone or did it just stop on its own? I read some people were told they needed new phones because of this. how bad does it suck if we need to get new phones because of tmobile?

I have the same problem too. its been about a week and t-mobile has not helped at all. i am going to try and reset all the service books again. let you know if that works

I pretty much gave up trying to fix it..I did different odds n ends for 3 days. Im noe demanding they give me a replacement..Since they dont carry the storm I dont know what they will do but they better do something! Here is an email with different steps the tmobile rim rep sent me maybe it will work for you!
