I switched to the Blackberry bold about 1 1/2 years ago and am experiencing the same dropped calls, lock ups, and constant loss of signal even within 100 yards of tower. This is the 2nd Blackberry replacement. I am presently working in Marseille, France and my "Global" Phone has no data or calling service. Same problem in Frankfort, Germany this morning. I arrived today to realize I couldn't call the people to come get me or even notify them I had arrived. I am subscribed to the international plan. I can't reach Verizon via E-mail, nor by cell phone with no service. A single Credit Card call was nearly $20 US. My wife called Verizon today from home to try and help; no help rendered. I have no extra apps instralled, and all settings are automation network selection and global. My job requires 24hr on call support and I presently have customers asking if I died over the weekend. Not Good!
