This eliminated lag issues I was experiencing with many versions of 6.0/6.1
Install this copy of Bitesms v6.0 from xSellize at
http://xsellize.com/topic/172492-k-bitesms-60/
1) Open in mobile safari
2) click the download
3) wait for page to load,
4) open the deb file in iFile [ex. bitesms_6.0.deb]
5) place the deb file in var/root/media/cydia/autoinstall
6) configure iMessage in settings app*
7) reboot your iPhone twice
*BEFORE 2 reboots, go to settings and sign in to (or disable) iMessage. Bitesms may cause SB to crash or lag if you configure after Bitesms installs
If iMessage is authenticated, Bitesms won't interfere when it is installed
Bitesms 6.1/6.0 freezes because
a) it is a crappy version of the crack (checks license each time you launch)
b) it is trying to authenticate iMessage every time you launch the app
The version I posted was cracked by Fabius and it doesn't freeze
whereas the version I got from sinfuliphonerepo DID freeze
(same Bitesms version, different crack)
cheers
