I have a BlackJack II SmartPhone and I want to upgrade from Windows Mobile 6.0 Standard to the new Windows Mobile 6.1. Are there any issues with the new Mobile 6.1 on smartphones? Also where do I go to download Mobile 6.1? I have checked the Microsoft site and all I find it information on Mobile 6.1 but now download. Also I will need the instructions on installation. Any help would be HIGHLY appreciated in this matter. Thank you in advance for your help.
