Okay i have a jailbroken OOB 1.1.2 u.k. iphone- and im able to use my non-iphone 02 sim-card in it.

Will this 1.1.3 (dev team) jailbreak let me still use the non-iphone o2 sim on it??

ALSO- will my sms's be kept? ive backed up sms.db just in case but will there be any issues?

(i just want 1.1.3 for the lifted sms limit!! 1000---->75,000)
