A hotspot is a site that offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.
Hotspots may be found in coffee shops and various other public establishments throughout much of the developed world.

If the phones got wifi you can connect to any wireless network if you got the password so i don't really understand wifi hotspot either lol unless it does something else.
Wifi Hotspot allows you to create a small wireless network from your OS7 BB using your data connection, setting name and password, so nearby devices can connect and access internet data.

I don't think this is what OP is asking about.
BaconMunch is right.
OP is talking about a "personal" WiFi, sometimes called "MiFi".
When you do not have WiFi connection or hotspot nearby, such as on the road, your handset, if so equipped, can activate the very local WiFi connection that wirelessly tethers your other WiFi capable device via wireless radio (data).
iPhone 4 has this capability and it is so useful. When I am on the road, I usally switch my handset from 9780 to iPhone and use my iPad via my iPhone for larger screen display of email, map or Googling or whatever else.
This is why I am looking forward to this capability activated on 9900. Then I can still use my iPad via 9900 on the road.
If the 9900 does not have this capability, or not activated due to carrier restriction, then it's a deal breaker for me.
