1) Should I install the symlinks as suggested in the "perfect ipot" tutorial? Also, what do they do? 2) Which bootloader is better, 3.9 or 4.6? If I used Ziphone 3.0 but then restored to original 1.1.4, do I now have 3.9? Can I/should I change it to 4.6? 3) What is IMEI? Thanks so much for your help.
