Default TCP and APN Help!

Please Login to Remove!

Just wondering if anyone would give me a little information on what changing your TCP and APN actually does, and how it's going to effect my curve.

I have heard that by changing these, you can get the curve's GPS function without the subscription, and also without accessing the internet. I don't have a data plan so I need to make sure that this won't cost me money...

What you have heard is only partially true. The APN setting is the internet gateway setting for your phone to access the internet through your edge carrier. For Rogers, it's

From my understanding, what happens normally with a blackberry data plan, is that all traffic, both email and TCP, flows through the Rogers BIS servers. When you don't have a blackberry data plan, you can still use TCP applications (such as JiveTalk) with a $5 mobile internet plan, by sticking into your APN settings. Leaving this setting blank will generally break TCP applications from being able to access the internet.

From my understanding of the GPS function on my friend's curve (with Rogers) is that it uses data and the GPS chip to triangulate it's position. This will use your $5mb data plan, but you will not need to sign up for any special GPS services like TeleNAV (dunno what Rogers uses).

Hope this helps.

Applications that need to access the internet from the carrier's mobile network need the access point name address (and, maybe, your username and password). Key point for you is this is data and may cost you extra unless it is included in the service you are paying for.
