Are you the type of person who is  considering the CORES on phones. Well here are the top android phones with QUADCORE built in your androids.

Here is a ROM for ARC/S users.. Based on Stock ICS 4.0.3 FW .562.. I don't own an Arc but this Rom is made entirely from Arc files... similar to my Ray Rom

Its NOT AOSP
Most of the Sony Bloatwares and Useless apps and other files removed for smoothness and made it look like AOSP ICS as much as I could do to give you stability, performance and Best of Both Worlds...
