Nextel Antenna
From what I have read it seems that nextel added the external antenna to there vesion of the blackberry because they wanted to give their users the best possible signal. Also from a couple of tests that I read on the internet it seems that in the 850 vs 1900 mhz tests there was no big difference. 850 mhz will penetrate wall slightly very slightly more, but neither pentrates walls well.
Hope this helps some.
