Default A bit confused with BB BES data traffic flow

Please Login to Remove!

I signed up BB BES plan with Singapore carrier SingTel, my company has BES server.

I am using 8700g.

I can phone call, SMS, MMS, WAP push, email, BB messenger with no issue. But I am bit confused with the traffic flow, I am trying to understand how data goes thru.

Q1: Are following data flows correct?

1. BlackBerry Browser: BB -> Carrier GPRS -> Corp BES -> .... -> destination site

2. Internet Browser: BB -> Carrier GPRS -> .... -> destination site

3. Other Appz: BB -> Carrier GPRS -> Corp BES -> .... -> destination site

Q2: I have read some threads here, saying that by using Internet Browser won't go thru Corp BES, my device has 2 browsers, a bit different, BB browser can not display Chinese web site while Internet Browser can.

I tried a SSH client, it connected to Corp internal IP successfully without going thru any VPN gateway, so I guess all data traffic will go thru Corp BES except Internet Browser? How does carrier force Internet browser to skip Corp BES?

Q3: If all traffic must go thru Corp BES, will that slow down the speed? If I am connecting to a Singapore local site with BB Browser, and our BES is hosted in US, that means data will go thru Singapore carrier -> US BES -> Singapore site?

Q4: If I have problem with some appz such as Google Talk, I tried GTalk but it prompted error said something like service book entry not found. In this case, which part of above flow should I look into? Do I need to apply for GTalk policy update from carrier or Corp BES admin?

Q5: Both Corp BES and carrier created lots of entries in my service book, some make MMS/WAP/InternetBrowsing working, some make email/sync data working, same question as Q4, in case of asking for a new service, who should I ask for?

Q6: Corp BES seems also control whether my device has phone call / SMS enabled or not. Does that mean, if Corp BES is down, I can't make phone call then?

Sorry for lots of questions, I am really new to BB...
