However, then your battery drains faster. I get around 2 days with my 7510 only because I have the auto-shutoff set at night.
Some corrections ...
Nextel Blackberries don't last as long as other Blackberries on a charge for the same reason that Nextel phones don't last as long as other phones -- the iDEN network is a power hog. Blackberry or no.
As for Blackberries on Nextel's network receiving mail "faster," that's not the case, either. If you're using Blackberry Web Client, the BWC polls the inbox every fifteen minutes to determine if there are unread messages, and then delivers said messages to your handheld. If you're using BES, the emails get "pushed" directly to your handheld, instantly. What carrier you're using is irrelevant. Nextel Blackberries are no more "constantly" connected to the network than are their T-Mobile, Verizon, Cingular, or Sprint counterparts.
