Dear All I have a few question, Hope I'll get some positive response. I have a HTC sensation running 2.3.3. I want to upgrade it to ICS. Is it good to go for a upgrade or just this phone should stay as it is, i want to know in terms of phone speed battery usage and other problems. If not then Can I upgrade it to 2.3.5 Gingerbread? and what is the procedure to upgrade. Thanking you in anticipation.
