Default BlackBerry with Sprint

Please Login to Remove!

Does anyone have any experience with the 7750 BlackBerry on SprintPCS service? Voice quality of unit, quirks, speed of browsing, use as modem, support issue, etc.

7750 is the DogBerry.... (slowest color BlackBerry)
Cannot be used as a modem.
Browsing is slowest among the BlackBerry models.

I would suggest you wait until the model 7250.

Well being a 7750 and running on a CDMA network be ready for slow device performance, one of the major down sides to the 7750 BB as a whole.

Isn't the 7750 supposed to be just the CDMA version of 7730? Is 7730 the same slug then? Or is CDMA the problem? CDMA data in the US has proved to be faster on data than any GPRS counterpart though.

It's not the network. It's the hardware.

Qualcomm (inventor of CDMA) more or less forced RIM to do all the CDMA processing in software rather than hardware. So as a result, the 7750 is really slow, and it's the DogBerry.

The 7250 uses a brand new chipset, that does CDMA processing in the hardware, so the 7250 is much faster:

Also, GSM/GPRS BlackBerry generally have much better battery life and RIM put more features in the BlackBerryOS of GSM/GPRS -- you no longer need BES/MDS to run TCP/IP Internet socket applications on GSM/GPRS networks. This isn't the case for CDMA networks (yet, at this time).

Also, it appears that Verizon (at this time) does not support BlackBerry as a modem for laptop on the 7250 (yet.)

Is it then safe to assume that all CDMA BlackBerry is "DogBerry", including the older B&W 6750 for Verizon and 7750 for Sprint? Whereas the 7730 GPRS version does not have this performance problem?

Seems to be just the 6750/7750 as Mark had mentioned the new BB 7250 for CDMA networks are using a newer chipset the the older modles. Follow the links provided by Mark.

I have a Sprint 7750... and it works just fine. The DogBerry put downs on this forum are a bit of an exageration, if you ask me. There is somewhat of a delay when I am navigating it, but then again, there is always going to be a delay somewhere with technology. Also, I am yet to not have reception with Sprint, which is great if you use it for business. Finally, I like the screen size of this BB, as opposed to the 7250. All and all, if you are a business user, the BB 7750 works fine, and Sprint has a great package, which my corporate BES supports. I would definitely recommend this to anybody who will use it to stay up-to-date on e-mail, and rely less on it as a phone. Also, check to see if you get a corporate discount, since I receive the largest discount with sprint at 23% off.
