I've been using a non-official v22.214.171.1241 for over a month and I'm so happy with it.
Everything works great EXCEPT the battery drain is annoying! So you need to charge it twice or more everyday.
Some users, however, claimed that if you wipe the bb with BSAK and then install the v126.96.36.1991, the battery drain will disappear!
I HIGHLY recommend this version
