GSM has always had this feature but CDMA phones for the most part cannot do this. Only the newer android LTE devices have been able to have simultaneous voica/data. it depends on the final chipset that rim has for its CDMA phones on if they can do this.
Is it perhaps also a carrier thing? Just tested it with my brother - I have a Torch 9650 on Telus and he has an iPhone 4s on Rogers and he was able to chat with me while he was surfing the net.
Rogers is GSM. AT&T is GSM. GSM networks since 3G have been able to do it. Some Android phones on LTE/CDMA can too but the general rule is CDMA phones can't and GSM networks can.
If the LTE phones have the second antenna that is needed, then they can. iPhone 5 cannot because Apple made the design decision to leave out this second antenna, possibly for space reasons.

Space, battery and cost. The same reasons will likely apply to RIM if they leave out this functionality as well.
Telus is HSPA. My understanding is that is not CDMA based. Please note I recognize that may be a stupid statement as HSPA may not ever be CDMA based (apples can't be based on oranges) but the bottom line is my understanding is that the CDMA/GSM issue is moot on HSPA. If anyone can confirm/deny or otherwise enlighten me that would be great.

If I understand correctly, GPRS/EDGE/HSPA are all GSM/UTMS protocols
1X and 1xEV-DO are CDMA protocols.
Tellus used to (still does) have a CDMA network, but they've recently worked with Bell to deploy a nation wide HSPA network. Tellus and Bell services are confusing because they still support the older networks, but basically all 3 major carriers in Canada are UMTS now.
RIM acquired paratek which is a company specializing in antenna design
I'd wager RIM will support the multi antenna needed to give both voice and data on CDMA networks
No, but common sense would dictate that those are the main factors in Apple choosing not to include the capability. I would have to assume that if RIM didn't include the functionality, it would be for the same reason. What other reason would there be? Spite? Just for lulz?

But seeing as ONLY Apple is doing it and Android and Microsoft aren't doing it the safer bet is RIM would be the same as the norm and not try and have LESS features than 2012 models

You may be right, and I never said that they wouldn't have it. I only gave justification for them not implementing it.

I believe the chipset is more than sufficient to run a side by side capability.

CDMA is voice only. LTE, at least for the carriers in question, is data only until they implement VoLTE ( Voice over LTE).
While the antennas can handle one or the other, they cannot handle both simultaneously.
With Apple, they chose to put out a phone that cannot do both simultaneously at this point in time with the carriers whose fall back system for voice is CDMA. They could have installed a third antenna which would be able to handle the voice while the other two handle data but decided to let people suffer until the VoLTE option was implemented by their carrier.
The question is, can the antennas that RIM is using handle both LTE and CDMA simultaneously or will they add a second antenna. Or will they just let their customers wait until VoLTE is implemented by their carriers�
