Good things to know for the jailbreak, unlock, and T-Mobile switch include the iOS, bootloader, and baseband versions, as well as the IMEI numbers. You can find all but the bootloader version in the iPhone's Settings > General > About section. The baseband will be called Modem Firmware there. For the bootloader version, I use f0recast by iH8sn0w at http://ih8sn0w.com/index.php/welcome.snow .
Best to all,

the bootloader version is irrelevant in a 3G, it does not have the iBoot lock like 3GS. All you need is the firmware version. I am guessing it was on 3.1.2 or 3.1.3.

I'm off work today so I'll get the details tomorrow when I see her again.
OK I read the jailbreak thread and yes, I can follow. The seller said the phone was already unlocked, is ther a way to tell? Does that have to be done after jailbreak?
What steps come after these to get TMo working?

you can tell if it is jailbroken because on of the apps will be "Cydia" you cannot get this app store unless you are jailbroken.
if you see this app, then it is probably unlocked. Just put a tmobile SIM in there. If you do not get service. make sure 3G is turned OFF in settings > General > Network.
If still no service, open up cydia, and use my jailbreak/unlock thread to download the correct unlocking app per the baseband. You find the Baseband version under General > Settings > About, and it will be called "modem firmware"
I am guessing it is either 4.11.07 or 5.12.01. Look at the unlockng thread to see which app to download, and it unlocks it very fast, then you will have tmobile service.

2 more things. If she is not getting data even though she is getting phone service with tmobile then
1) make sure you enter the APN settings for data and MMS, they can be found in the stickied thread in this forum.
2) if data STILL does not work. You have to call/chat with tmobile and tell them you are using an iPhone (they don't care, they actually have better iPhone support than ATT) and tell them to please change your "data provisioning" for the iPhone. They will know what u mean and make the change, after about an hour the data will work, provided you have entered the APN settings correctly.
