Jailbreak Help! Ios 5.0.1 iphone 4, won't unlock

Alright so I have a untethered jailbroken iphone 4 running ios 5.0.1, I download a cydia tweek that removes the slider on the lock screen thinking that instead of sliding the slider and then entering my password, I could just type in the password. So now there's no slider and I can't figure out how to unlock it, I tried re jailbreaking it but it doesn't change anything and restoring it through itunes would download the ios 6 which I don't want, how should I get the slider back? Please!

Cool

You can't unlock the iPhone 4 with cydia tweaks anymore. It all depends on your baseband, which 5.0.1 patches. You need to have your phone factory unlocked (permanently unlocked). If you know somebody who has AT&T service, you can have them call and provide the IMEI number, and AT&T will factory unlock the iphone for you. (That's what I had to do for t-mobile).
iphone 3gs' are the only iPhones that support ultrasn0w and such.

If you would like a permanent Unlock you can get one at http://attiphoneunlocker.com/
Once you receive your email to confirm that your handset is unlocked, for the iPhone simply connect it to iTunes which will complete the unlock.

Once your Unlock has been processed just follow these simple steps:

1) Open iTunes on your Mac or PC (verify you have internet connectivity).

2) Connect your iPhone to your computer using the USB data cable.

3) Backup and Restore your iPhone using iTunes.

4) Once your iPhone is restored it will have the Factory Unlock in place!

There's a possibility the code will be returned as NOT FOUND and its not in our control. If that happens you will be refunded.
