Something is still not clear here, and I need to provide some contextual background. Several years ago my best friend, the Senior R&D Testbed Manager, Office of the CTO of Nokia (Palo Alto CA), was at my home for a meeting and he immediately identified the noise emanating from my computer speakers as "GSM interference" [from my RAZR V3] and that led me to begin a long thread here in comp.dcom.telecom. I still have and use my RAZR V3 solely for telephony which is all I need since I have more computers in my home office than do most small offices and businesses. In other words, I have no need for a smartphone or any texting or mapping or app capabilities at. The GSM interference was so annoying (and my friend commented it's also a big problem in all the conference rooms at Nokia in Palo Alto) that I was forced to leave my RAZR in the kitchen about 40 feet away. Oddly, approximately a year and a half ago, a new icon appeared on my RAZR's display and I had to look it up in the manual. The icon is that for GPRS. At the exact same time, all GSM interference ceased and I now can sit my RAZR down on the table along the computers without any problems at all. There's no information in the RAZR manual about GPRS except identifying its icon (e.g., no documentation how to enable or disable GPRS and/or whether it augments, complements, supplements and/or replaces GSM) and the only more-or-less useful info I found is this Wikipedia page: http://en.wikipedia.org/wiki/General_Packet_Radio_Service which states: "General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications (GSM). GPRS was originally tandardized by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP)." Given AT&T's EOL announcement for 2G service doesn't mention GPRS and that GPRS is also functional under 3G (which I presume AT&T will retain for the foreseeable future), can I presume I will be able to continue to use my RAZR V3 via GPRS beyond the 2G EOL? The phone is in excellent condition and has served me well since 2004, and given I'm now retired I need to be very aware of how I spend money nowadays. I would appreciate any insight regarding GPRS continuation on the AT&T network. Thad

I guess my old Nokia 6610 is all either 2G or even more primitive, as are all my Motorola TimePorts (P7389, P280, T250, et al.). But where would my RAZR V3 (original), SLVR L2, and LG cu-400 fit in? To be deprecated and rendered redundant? Or still OK for the 3G/4G-only era? TIA. And cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP.

CSD stands for Circuit-Switched Data -- it's how T-Mobile (US), at least, handled WAP browsing back before there was GPRS for data transport, and was offered on such handsets as the Motorola Timeport P-7389, P280, and others. Once GPRS became entrenched, T-Mobile (US), at least, shut of CSD services, and those handsets (and their kin) became useless for WAP browsing in the US (though Polish GSM providers like Orange (PL) still offered CSD data service as recently as a-year-and-a-half ago -- and charged extortionate air-time rates for the privilege of using it :-) ).

Russia's space agency said the failure of the upper stage of the launch atop its workhorse Proton rocket led to the loss of Indonesia's Telkom-3 and Russia's Express MD2 satellites. The error happened after takeoff from the Russian-leased Baikonur launch pad in Kazakhstan late on Monday. The total loss of the two satellites was estimated at $100 million to $150 million, a space industry source told Interfax news agency. ... http://www.msnbc.msn.com/id/48552104/ns/technology_and_science-space/

Subject: Arkansas AG takes on the credit card telemarketers Message-ID: <slrnk2a7ot.t0h.jhaynes@Frances.localdomain> I see by the morning paper that the Arkansas Attorney General has filed suit against some individuals and companies in Florida for violating the state and federal do-not-call lists, and also for misrepresenting the credit cards they are peddling. Says they offer a low rate to start but then it jumps to a high rate after a few months. And that with no authorization from you they transfer your credit card balance from your other card to theirs. -- jhhaynes at earthlink dot net
