Nokia Siemens' 'Multiflow' for HSPA+ Lets Phones Talk to 2 Cells
What it really means
these are chips being developed by someone other than ATT
It will be some time before they are incorporated into PHONES and TABLETS....
Making a 'simple software change' at the towers won't do anything until such time as a huge number of customers have the new devices with the chips.
Take your hate blinders off.
In March of 2010 I gave up on waiting for ATT and went with Verizon, cause I knew Verizon would be the first in the U.S. with LTE.
One, Multiflow will not double capacity. It appears to be a soft handoff scheme for HSPA+ data. It will improve data rates near cell edges where interference between cells normally limits possible data speeds.
Two, Multiflow will not affect dropped calls. Calls do not utilize HSPA+ enhancements; calls travel over standard W-CDMA, which can already utilize soft handoff.

network resources, delivering up to double the data speed and up to 50% faster response compared to existing HSPA+ networks." And: "...it reduces imbalances that typically occur in network resource usage, and increases HSPA+ speed and capacity.”

Yes, now go back and read the article again. Note that it states "cell edge" at least three times. I stress again that Multiflow appears to be a soft handoff technique. It can improve data rates at cell edge, where C/I ratio is generally lowest. However, because data has to be backhauled to a second cell site, Multiflow may actually reduce capacity for other users.
Trust me. ...

the software change would be needed to accomodate the new chips in Nokia phones or of manufacturers who utilize their chips....
until such time as the chips are incorporated and a large number of customers have those devices, any software change is meaningless
