Manually enable/disable Internet access

[Tplane37]

I am new to the Pocket PC/WM6 tweaking, so I will likely desire step buy step instructions until I get the hang of things. If there is a "Mods for Beginners" thread somewhere on here, I'd enjoy a link to it.

My question pertains to using GPS programs on my Verizon phone. I am looking to purchase and instal Microsoft Pocket Streets 2005 on my phone in the near future. Verizon tells me that it will work so long as it says it works with WM6. My concern is being charge through Verizon for using a GPS Navigator that is not VZW Nav. I would like to be able to disable the internet service on my phone (XV6800) so that it cannot automatically connect to the internet for updates and so on. This way I have to manually allow any program to go online for anything. I do not have, nor do I plan, to put a Data plan on my phone, as I alread have a Broadband Access plan that is under contract, and is their Unlimited plan. Is there a fairly simple way to do this?

Or, another option I was thinking of as I screwed up my phone while attempting the Sprint ROM mod (bought my phone two days ago, warrentied it yesterday), I had managed to get to the point that my phone number was no longer on Verizon's System and had found it's way back to the number pool. Even my service plan was switched back to a National plan instead of the Family Share plan I had....I am curious if their is a way to go in with the ##778 option to switch my Broadband Access plan to my Titan while keeping my 6800's cell number and my AC595U's price plan (since they refuse to let me have Unlimited Access on any new Broadband plan...and I don't want to loose the unlimited acces.)At that point, I wouldn't care if my phone logged into the net to get extentions and so on.

Can anyone help out with either of these questions? I am willing to clarify and accept critisism if it is needed. Thanks.
