im using 930 mhz for 3 days now and got no major problems except that my battery drains faster because i frequently browse. also I notice that my phone is much warmer than before when using the cpu for 100% however when idle phone stays much longer than before.

overall the performance is great i even compare this phone with my friend who has got a stock cpu speed and this phone is way much faster than his. his phone suddenly feels obsolete lol
