I purchased an unlocked for t mobile iPhone 3GS on eBay, here's all the info I have:

So the issue I'm running into is the phone keeps jumping in and out of service/no service. Yesterday i had service all day, no issues. I woke up this am and the phone had no service at all. I've had it since Friday of last week and the issue just continues to come and go. Is there any help anyone can offer?

I used a BB Curve previously and also got a new SIM, thinking maybe that was the problem. However it continues to happen.

Thanks to anyone who can help!

Go to settings and turn off 3G.
That's what happens when you leave it on and you're using it on Tmobile USA.

3G is off, and always has been. It's really strange, the phone will hold a signal for hours at a time and then simply lose service and bounce in and out. I haven't been able to find anyone with a similar problem. Thanks though.

Did you try to reset network setting? it might help.

Oh that sucks.
Not sure what other thing would cause that. Try what CRX said also.
The last option would be to restore and re-jailbreak and unlock but that can get complicated so you gotta be extra careful.
