I found this while perusing the Developers Conference Blog, a lot of new users have trouble understanding what all the browsers are for, so here is a break down.
5 browser names and their various aliases:
BlackBerry Browser (”Corporate MDS”, “MDS”, “Enterprise”)
Internet Browser (”Public MDS”, “BIS-B”)
WAP Browser
Hotspot Browser (”Wi-Fi Browser”)
Unite Browser
1. BlackBerry Browser
Only available if device is connected to a BES at your company
All traffic goes through the MDS-CS component of your company’s BES server
Can access resources inside your company’s firewall, such as intranets and desktop PCs
However, it’s also restricted by that same same firewall, just like the PC at your desk
All of the other browsers are outside the firewall
2. Internet Browser
Virtually every device has this browser; no corporate BES connection or email setup required
All traffic goes through one of a few MDS-CS servers hosted by RIM
Sometimes requires that an APN be setup in order to work (on GSM networks)
3. WAP Browser
All traffic goes through the WAP gateway hosted by the carrier
This is the only route where no RIM-owned servers or RIM-produced software are used during communication
WAP gateways vary from carrier to carrier, making problems often difficult to resolve
No MDS-CS present to perform content optimization; entire web page is sent to the device
4. Hotspot Browser
Uses Wi-Fi network to route traffic
Sometimes goes through the BES’s MDS-CS and sometimes just on the local network
Device setup makes this route somewhat unpredictable
Generally very fast throughput, making pages load more quickly than all other browsers
5. Unite Browser
All traffic goes through the MDS-CS server running on the Unite server on your home computer
Common Problems When Using the Incorrect Browser
The web page won’t load
web site is inside the firewall and you’re not using the BlackBerry Browser
web site is blocked by your company’s firewall and you are using the BlackBerry Browser
web site is carrier-specific and you’re not using the WAP Browser
web site is hosted on your home PC and you’re not using the Unite browser
Far more data than required may be downloaded
when data flows through MDS-CS it is optimized for the device, including reducing image sizes, compressing text, and optimizing the HTML DOM tree
using the WAP Browser the entire web page must be downloaded, even if images are 30x the size of the screen
Slow page rendering
data flowing through MDS-CS also undergoes optimization, such as pre-compiling JavaScript and modifying the HTML layout for a smaller screen size, increasing layout speeds
using WAP Browser forces the device to do this work, which takes longer
Larger financial cost
since more data is transmitted when using WAP, plans that pay per megabyte will be more expensive
Wi-Fi is generally free, so using it instead of cellular network saves money as well
