I am now with Cyanogen Modem 7.1 with the Hot fixes. The previous flash did not work because i did not wipe the data. So looks it was conflicting.
This clean install give a better picture of this new ROM . Yes, as you said, there is a great improvement in battery Life. I am charging it only after one and half days. The battery is very much stable.
Over/Under clocking the CPU gave me a very good result. I am now totally satisfied with Android 2.3 with this MOD.
But you did understand one thing wrong. The Network Carrier name is displayed if i insert the Vodafone SIM. If i Insert different Operator SIM, it is showing their Network Code instead of the Name. In INDIA, i have the Operators like Airtel, DOCOMO etc. When i insert the Airtel//DOCOMO SIMS, it is not displaying the carrier name, instead it is showing the Network Codes.
What i mean, if i am roaming outside my Home Network/country, I am not getting the carrier name. It is Just showing the Network Code instead. So i would not be knowing which network i am currently connected. Because if i am connecting to the network which are not a roaming partner to my network, then i would be charged double. This is one the concern i am seeing with this Mod.
Could the Mod Developers, please advise on this.
