Let me explain.
1) during a call you phone (BB, Motorola, Nokia, SE, etc) will open a voice channel to the network hence the reason those 3d arrows stay there during a call.
2) GSM based cellphones every 30 to 60 seconds WILL communicate with the network. Basically saying "peek a boo! I'm still here I'm still on, anything on the network change yet, please let me know". ANd the network will provide updates to the unit ...
3) updates from the network include .... period changes to another cell tower = load balancing, IP address changes = seemless, features on the switch ie Call forwarding/waiting/roaming changes = BBs are exceptional in this regard because ANY of these changes show up on the BB's in REAL TIME! NO other cellphone/smartphone does this. For instance If I work at Rogers and make a change NOT in you billing account but on the switch for your mobile # or IMSI (SIM Card) say removing call forwarding ... within a heartbeat you will NO LONGER see this a selectable option in the menu of your phone app on the BB.
Considering that Nokia, Ericsson, & Nortel make switches that ALL GSM carriers use Rogers is exclusively Ericsson, TMobile was all Nokia & Ericsson (could have changed) their phones don't provide this real time changes in the menus not even in MS Mobile phones do this.
Does this help?
Proof hold a regular S40 or SE phone near a TV set ... turn the speakers up and you'll hear that Krazzie noise going off through the TV speakers - even a samsung or motorola or nec gsm phone will do this. 2 watt phones like all BB's or most of them will be a stronger and louder signal.
Jagga, thanks a for a technical explanation - it makes sense.
BBs are awesome
No wonder people love em to death
