Sony Ericsson GC79 802.11B Wireless Adapter

I purchased the GC79 with TMobile service. The connectivity was routinely poor when wireless, even in places TMobile had a strong signal. I use a TMobile Sidekick which performs wonderfully, However, with the GC79 you can get online but navigating is like AOL dial-up in 1995: painstakingly slow and tedious, with frequent connection drops. You are better off finding a hotspot or going to the library.
