I was on tweaked 2.2, pbj 0504, solid ics. I attempted to edit the build.prop file with es and ended up crashing my phone. I took the ota to fp5 and am pretty unhappy with it in comparison to fp1. The radios don't seem as good and that's kind of a big deal to me.....stock fp1 was snappier and than stock fp5 all together.

Fp5 has been much better for me. Far better 4g connections.
