I have an 8130 Pearl v4.3.0.97. After flawless synchronization with Outlook 2007 for several weeks, my desktop outlook calendar was completely erased. The address book sync still works. The data remains on my phone calendar but will not move to Outlook. Verizon couldn't fix the issue so they sent me over to Blackberry tech support. Blackberry tech support says a patch for this known issue has been developed and this patch has already been sent to Verizon. Verizon first tier tech support didn't know anything about it and can't tell me when this updated software will be available . Does anybody out there have this issue and if so have your carriers addressed it?
