I have the signal meter set to display the dBm reading of my Sprint iPhone 5 connection. My phone appears to oscillate between two signal states. One is a strong connection which reads anywhere from -70 dBm to -91 dBM, and the other is worse, often showing -106 dBm. What bothers me is that it will oscillate between these two states while sitting in the same spot on my desk. It also sometimes drops 3G connection when cycling to the worse signal state, and data transfer speeds are much worse. My wife's iPhone 4S (iOS 6) displays a relatively consistent signal while sitting on the same desk and outside in use. It never oscillates or cycles as my iP5 does. Moreover, the iP4S signal is always -1 or -2 dBm better than the iP5 even in its better state. Are you experiencing similar signal cycles? I'm trying to figure out if there's something wrong with this unit's antenna or chip. When I first got it, it wouldn't hold a 3G connection for more than a second. Now it holds the 3G signal better, but has this oscillating or cycling problem. What should I look for in the Field Test panel to investigate this further? I've tried resetting network connections, tried doing a data profile update, tried resetting and restoring, I even tried activating a new ICCID sim card (which had no effect, went back to my original one). This is a replacement unit (bad bluetooth module on the first one), and I hate to be "that guy" going back again, but this is bothering me. Thanks!

My daughter has an Iphone 5 and lives in Lawrence KS, where Sprint has LTE service. She called the other day and said her phone was only connecting 3G. Using my experience with the HTC EVO LTE and its connection issues, I told her to toggle the airplane mode. Eureka, it immediately connected to 4G. Seems like the connection algorithm is not perfect on the Iphone 5 either.

Does anyone know how Sprint and VZW is doing in Pre-Order Sales? AT&T: http://www.macrumors.com/2012/09/17/iphone-5-pre-orders-set-new-sales-record-for-att/ http://www.macrumors.com/2012/09/17/apple-announces-over-two-million-iphone-5-pre-orders/

I just ordered a white Iphone5 32gb for my daughter at Best Buy.. The guy here in OP said they were not close to filling their allotment. I could only order from Sprint online, and the apple store said they were on a 2 week delay now..

Well Joe spilled some of the beans at the investor conference...Saying that the companies agreement with Apple is similar to both ATT and VZ, also that Sprint is NOT being held to ANY 4G LTE coverage requirements.
