For those that weren't following the respective G11i Pro or HD7 Pro support threads, here are the breaking news:
Both phones can now support one of the most desired features - SIM2 will be reachable even if there's an active data connection established on SIM1. The data connection will be immediately dropped when a new call is incoming from SIM2 and the download will be automatically resumed after the call is over.
In my opinion, that's the most important feature of the newly released ROMs. Although, there are many more changes / improvements... such as battery consumption reduction, better memory management, speed improvements, many bug fixes and, of course, some cosmetics changes. Here are just a few eye candies.
For the most distracted ones, here are the links to the support threads:
