Curious: but for OmniPoint and MetroPCS, I followed your footsteps exactly. Late summer of 2000 I returned from Belgium with an unlocked 3-band Motorola TimePort of the P-7389 persuasion, and sought a carrier for it. Only choice in my neck of the woods would have been OmniPoint -- but they had zero interest in selling me a SIM or making a customer of me and my TimePort. A few days later (once Labor Day had come and gone) it was no longer OmniPoint, it was VoiceStream, and they were more than happy to sell me a SIM and make a customer of me. And customer of VoiceStream, and later T-Mobile, I've been ever since. What drove you to MetroPCS, if I may be so bold as to ask? Cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP.

You might have a DVR, in which case recording the HD version will consume several times as much capacity as the SD version. You could also have better reception on one channel than another. While all cable channels are "supposed to" be equally clear, in practice it doesn't work that way. Before HFC, weak signals on some channels were pretty common. Where I live, it's a different problem; the transmitters are nearby, so OTA signals infiltrate house wiring and interfere with the QAM streams. And since the HD and SD are on separate frequencies, if one is hit, the other might work. Back in the analog-TV days, Continental figured out that they should not run local TV stations "on channel", as the infiltration would cause ghosting. So the VHF OTAs were moved up into the 20s. Translating cable boxes hid this, so only cable-ready sets noticed. But they didn't coordinate their hidden QAM channel layout with DTV hidden channel assignments. So Comcast stuck the 10-channel multiplex that carries almost all of the local OTA SD stations on (IIRC) 571 MHz, overlapping TV channels 30 and 31, both of which are full-power DTV channels. Hilarity ensued. (DTV channels are hidden; stations advertise "virtual" channels, their pre-DTV numbers.) Which they haven't fixed; I've had to do a lot of tweaking of the cables around the house (not good quality, self-installed by a previous owner) to get usable reception. -- Fred R.
