Anyone using and iPhone 4 on t-Mobile?

I am sick and tired of not having any service during the day on AT&T and I don't want to wait for the new iPhone to switch. So I was thinking of unlocking my phone and temporarily moving over to T-Mobile by using their $50/mo unlimited prepaid plan.

If anyone has done this, or something similar and can offer their advice or just comment on your experience, I would appreciate it.

Thanks.

Lots of folks on T-Mobile are using unlocked iPhones. The results are good as long as you're satisfied with EDGE only. The 3G and 4G frequencies that T-Mobile uses are not compatible with the iPhone. Now whether or not that changes when the buying of T-Mobile by Ma Bell is finalized, no one knows.

EDGE would be fine with me as long as it's temporary.

Hopefully filing/cutting down the SIM isn't too difficult to make it work with my iP4.

Don't know if this is relevant to your situation, but it does look like the iPhone is coming to Sprint (and maybe other carriers) with the release of the new one ... now set for sometime in October ...

Yea I saw that and it peaked my interest. There have been general complaints that their 4G service is barely faster than AT&T's 3G, especially in my city. But then again, their pricing is better and they have unlimited data (for now).

My game plan is to just dump AT&T now and go prepaid on T-Mobile until the next phone comes out and I can evaluate options then.

It'll be nice to have more choices!

Again, keep in mind that T-Mobile is being bought up by AT&T. My bet is that you can kiss those nice rates goodbye when that happens. And it looks like it's going to happen by 2012 or sooner.

As for Sprint... I wouldn't give them a nickel of my money. They had and possibly still have the worst customer service that I have ever experienced from any phone carrier. I'm currently with T-Mobile (no iPhone) because of their low rates and good customer service.
