Simply Everything vs. Everything Data: Internet usage changed? Tethering exploit?

[Rento_VW]

So I currently have the Simply Everything plan... But I barely actually talk on the phone, I only text and use MSN, and the like.

What i'm wondering is, is the only difference between Simply Everything and the 450/900 minute Everything Data plans is the cap on time usage of talking during peak hours?

I use my phone for internet when i'm away from town on the weekends, like when i'm out in the desert, absolutely far away from any form of internet...

It looks like i've used over 3XX MBs of internet this pay period, and slightly over half a gig of internet a few months ago. It's not I use it for downloading stuff, just casual surfing the web and getting information to repair the off-road vehicles we use out in the desert.

I don't pay for tethering... I just use internet sharing, but only because out there, you're always rushing, hooking the phone up to a notebook and using the bigger screen and keyboard makes everything faster. Is it easier to get caught with a Everything Data plan vs a Simply Everything plan?

I just got off chat service with a sales rep and they said I won't be charged anything if I change my current plan over to a 450-ED plan.

Didn't ask if there was a way I could perhaps get my bill that is due in 2 days dropped $30 or so today if I were to actually switch over to a 450-ED plan effective within the next few hours. Perhaps I should call in a bit and ask?
