Well our house hold has two Skyrockets. One just updated to the leaked ICS and one on gingerbread. And lemme tell you, I have been doing some testing and I have noticed two major improvements.. Number one..My signal on the ICS is double sometimes than on gingerbread! And the battery is also slightly better.. I put the phones side by side, right on the couch and watched the signal meter for like fifteen minutes and the phone running ICS was always WAY better signal.. Very interesting...
