Nope, I wouldn't buy the new phone yet. It's not the firmware you need to worry about, it's the baseband update included with the firmware.

So in other words, you can't use a newly purchased iPhone 3G on T-Mobile...yet. Should the dev team update yellowsn0w to work with 2.30.0 baseband, you'll be all set at that time.

Or spend $10 on eBay and get Turbo SIM.

Hopefully they will be able to update yellowsn0w soon.

But the new phone you buy might not have 2.2.1 on it yet it may have 2.2!

I bought a new iPhone 3G on Tuesday, it had 2.2 on it, its now running on T-Mobile. So you might not have 2.2.1 on the iPhone you buy
