I have an ipod touch, but I'm considering going to an iPhone. I know very little about the unlocking process, but a lot about jailbreaking. I have a mac, and I'm not sure what I would use to jailbreak and unlock it. I've heard a little about iLiberty and ziphone. After that, I can use it with T-mobile no problem? Right now, on my plan, I have unlimited texts, picture message, and aim, so would all of that apply with the iphone? If I bought the $5 monthly t-zones or whatever, could I have internet access everywhere? Could I use it just fine without any extra charges to my bill or getting busted from t-mobile?

Point me to a thread if there's already one like this made.

EDIT: Also, if it's possible, I'd prefer to stay at 1.1.2

iLiberty and ZiPhone are for 1.1.3/1.1.4.

Just use that and one of those two to unlock, and basically you get everything the same with your T-Mobile plan. Minus AIM and MMS (only SMS), since that prolly wont be available till 2.0 comes out.

You can use Pwnage Tool 1.1 to now "pwn" your iPhone and load a custom restore .ipsw for 1.1.4 and it will pre-unlock/jailbreak your iPhone so should you need to restore, you use the custom .ipsw and you're right back on track.

If I bought T-zones would I have internet? And sms is the same as text messages correct? I'm not familiar with mms.

MMS = Txting with pics and video.

I am not familiar with T-Mobile's internet plans, but I am just guessing yes.

All right great! Thanks for the info Hara! So once it's unlocked, I'm good to go? Nothing more?

I guess I'll have to search for a guide for 1.1.2

Yeah pretty much. I wish I had more info, but I don't have an iPhone to test with (else I'd unlock mine and test on my friend's T-Mobile SIM).

There is a hack to get TZones working on iPhone, should be in installer under bigboss's apps.

There's absolutely no point in staying at 1.1.2. 1.1.3 has much more/better features than 1.1.2, and practically every app in Installer supports 1.1.3/4. 1.1.4 is just improvements on what's broken in 1.1.3 and can be easily jailbroken/unlocked as well. Use iLiberty+, one click, and you're done.

I agree, I originally had 1.1.3 on my touch, but found that it was too buggy and took too much time of fixing things that didn't work, so I settled with 1.1.2

The only reason why something would be buggy would be because of a bad upgrade. A restore is almost guarenteed to fix any problems. And, since iTunes backs up all of your setings, call log, SMS, etc., there's no point to not restore, you just have to wait the 30 min - 1 hour while everything syncs back up.

Why stay with 1.1.2? 1.1.4 is much better.
I recommend to unlock using iLiberty.
Personally I had no troubles with ZiPhone, but a lot of iPhone got Wi-Fi troubles.
Use ZiPhone if you really know what you're doing, it is very powerful but very dangerous for
first time users.
