I got a wierd problem, I unlocked my iphone successfully using the iUnlock, Here is what i did:

First connected the phone to iBrickr and installed the installer
then installed the iUnlock.pxl and also installed few other apps like Terminal, Lights Off & Tic Tac Toe. Then ran the iUnlock, after 20 mins, it unlocked my phone successfully, then when i put my sim, it said invalid sim, so i downloaded PAYCAY and activated it. Till here everything was great but later when i tried to uninstall the apps which were installed either with iBrickr, it just does not uninstall the existing apps nor it installs new apps. I dunno what to do

Please help ????
