I got a G1 today and asked for an unlock code. My first question is about how long should it take to get the code via e-mail? My second question is...my dad has AT&T Go and once the phone is unlocked, we'll try putting the SIM into the card. Will he need to get an add-on to his account for data? He has a basic flip phone and has the $40 a month plan I believe...will he be allowed to use wifi without the data package?
