On Making the Switch to Sprint

With last Friday’s iPhone 4S launch, the stars were finally aligned to allow Carolyn and me to make the move off AT&T’s accursed network onto Sprint’s. It involved paying an early termination fee and buying new phones, but after the zillionth dropped call (even with our additional Microcell), we’d had enough.

A few thoughts on making the move:

– First off, reception is _way_ better–5 bars vs. 1-2 on AT&T.

– Carolyn can probably explain the reason for it, but the switch in network types also means the call defects are different. AT&T’s GSM network would just not make calls (call failed when dialing), or drop them suddenly with no reason. Afterward, it was typically hard to get a solid connection. The two times I’ve had problems with Sprint’s CDMA network, the calls got “static-y” for several seconds, then dropped. A call-back would result in a crystal-clear connection. Is this a cell tower/band switching thing?

– Data speed seems the same or better with Sprint. I’ve noticed, however, that most of my data traffic these days is moving over Wi-Fi (Thanks for the free Wi-Fi, Starbucks!), so 3G data may not be as important as it once was.

– I went with Sprint over Verizon mostly due to the total plan cost for a family being much higher on their network vs. Sprint’s.  I hear overall good things about their network, though.

– For the first time, I recouped a ton of cash with no trouble whatsoever by selling back my now-obsolete phones. Sprint has a buyback program which instantly credits you about $250 for an iPhone 4 and $180 for the old 3Gs Carolyn had been using. Redemption was as easy as bringing in the (wiped) old phones into the store. Nice! (I also got $100 instantly on eBay for the now-obsolete Microcell I’d bought in a vain attempt to have my phone calls improved at home by routing them over my stupidly fast internet connection here. The Microcell managed to deliver 5 bars, but just as many stuttery/dropped calls as before. I never figured out why, despite two advanced troubleshooting calls with AT&T).

– If you’re thinking of moving over to Sprint, make sure to take advantage of discounts available to credit union, AAA, or military folks. I hear there are often corporate discounts as well. The discounts tend to be about 10% of the monthly bill.

A Sharper Image for Blurry Photos

Anyone who shoots with a digital camera should have a look at this demo video from the latest Photoshop conference (the good stuff starts at about 1:30).

Although the algorithm can’t make awful images into works of art, it seems to do a masterful job of making unusable images usable again. I’m also curious to know more about the “blur kernel” mentioned in the algorithm. I’d been under the impression that blur of this sort was a simple shifting (e.g. you jiggle your arm to the right as you take the photo) — the reality looks more complicated.
