My corrections to CSD are based on

ETSI TS 101 038 V7.0.0 (1999-08)

Technical Specification

Digital cellular telecommunications system (Phase 2+);

High Speed Circuit Switched Data (HSCSD) - Stage 2

(GSM 03.34 version 7.0.0 Release 1998)

available from ETSI

[edit] Availability: My thoughts on the unverified claims

The author's research assumes the user has "free minutes" already purchased which he/she can use for data at little or no extra expense. A mobile connection dedicated to a data application would not have a "bucket of minutes". Regular short bursts of data (a KB or two) would be extremely expensive once rounded up to the minimum 1 minute rate. The difference could be $0.50 on CSD compared to $0.01 on GPRS for each 1KB transfer. Hence original research shouldn't really be on Wikipedia, despite being interesting. In sure facts can be extracted from the section.~~k —Preceding unsigned comment added by 203.152.115.183 (talk) 21:48, 20 September 2007 (UTC)
