Finally I upgraded from GB to ICS, and it was no problem at all. However I am experiencing that many apps are FC all the time. Especially Exchange mail (corporate) is a HUGE problem. It recieves mail, and syncs like a charm, but every time I try to open a mail it FC. Everytime! Also the HTC_imei_mod keyboard is giving me some problems. It works, but when I try to push one of the suggested words in the autospelling it FC. Any suggestions?
