What is the latest patch for BBE100-4 -pushed by BBMo, or available otherwise? I have been on ABX563 since my purchase in January. Also, what exactly is a prd number, where can I locate it on my device? Finally, would a manual update entail a complete reset where I have to restore everything from backups? I am data roaming in Europe w/ my AT&T in SIM2, local phone service in SIM1. Feedback would be much appreciated. Thank you. Matt.
