No - I do plan on the unlimited data plan; it’s just that I have large attachments in my e-mail sometimes and if you go over 5GB/month, I’ve heard that Verizon’s been “throttling back” lately to 700 kbps (which is a pain) or even terminating service.
I doubt I’d hit that 5GB amount, but it bugs me that I might be limited in any way. And I’m not worried about battery life, I wind up charging my phones nightly anyway.
