This method describes how to unlock the Galaxy Tab P1000, which is the first generation Galaxy Tab. First of all, if you are running a US firmware, get the European firmware to get the Phone software. Then, on your phone dial *#7465625# and check if the Network Lock is set to [ON], if so then your phone is locked, so continue.
1. Use Superoneclick to root galaxy tab (the other z4root method may work as well, but this isn’t what I used).
