Phone doesn't get signal until reset

[honduh]

I have had my touch since July, and I have had a ton of problems with it lately. The biggest problem I am having currently is a signal issue. I do not get signal in one of my classes, and after leaving the class my phone will never re-aquire a signal unless I soft reset. This is very annoying because I have to reset my phone 2-3 times a day. The phone acts like it is in airplane mode, usually it will show the tower icon but have no bars...then after a reset I have full signal again. I am unable to make/receive calls or texts until I reset either.

I am really unimpressed with the reliability of this phone. I hard reset the phone around thanksgiving and I have kept it stock since then, and it is still giving me problems. I have the latest official sprint rom installed, and my radio is up to date. Should I file an insurance claim and try and get a diamond? or is the diamond just as bad/worse than this phone? I am almost tempted to venture into iPhone land because my phone gives me so many problems daily...

So if hard resetting your device does not correct ths issue then you are looking at a hardware problem...That means its insurance time...
