iphone 4, 4.3.3, JB w/sn0wbreeze - multiple problems

[bmarkoff]

iphone 4, JB on 4.3.3 using sn0wbreeze, BB-01.59.00. previously JB on 4.0.1 using jailbreakme.com.
ever since this latest JB, I have had some annoying issues:
1. many times throughout each day, I apparently lose signal, and it says NO SERVICE. this never happened before.
2. my home button does not seem to react properly all the time. I often must hit home button 2 or 3 times, until it either closes the app, etc.

could this be from the JB, or perhaps an app or cydia tweak. it is just very frustrating.

Well.... the unlock comes from a mobile substrate program Ultrasn0w. Software apps, especially pirated software and tweaks can easily interfere and create problems. Sluggishness is another symptom of incompatible software apps. So ... start removing stuff starting with the last installed and see what happens.
