I, too, have sprint, use lg musiq. (I do not recommend this phone). Data port and AC charging port are the same, meaning that as usb connection , your good as long as battery holds out. (abt 2-3 hrs). Then you have to go offline to charge phone.

Have tried bluetooth. here is what I found after 6 months of f***ing around: could not pair w/toshiba-intel setup; moved to hp dongle and broadcom(widcom) stack - that setup was as solid as an agoraphobic stuck in a walmart cashier line - have changed to iogear dongle w/broadcom stack. Works like a charm, bt connection, though slow, is solid, w/very few discos.

lately have had same connection problems as others here.

cannot use port 6347 - port is unavaliable ???
have a firewall signal on tray, came out of nowhere.

also use peer guardian2, (forever), and looking at reports, shows blocks on "limewire" at addresses such as 70.5.224.106
99.201.80.14
68.246.97.127
among others. What is that about?? Never before have I seen this....

oh... latest versions of everything... xp pro sp3, limewire xxx-8 pro, java 1.6.10 (no issues b4), asus laptop, centrino dual, 3g ram, etc.

anybody find anything out?
