PHILADELPHIA (AP) – Their thumbs sure must be sore.

Two central Pennsylvania friends spent most of March in a text-messaging record attempt and ended up exchanging a total of 217,000.

Twenty-nine-year-old Nick Andes and 30-year-old Doug Klinger relied on their unlimited text messaging plans to get them through the escapade.

A spokesman for Guinness World Records didn’t immediately return messages Tuesday asking whether it would be certified as a record.

Andes was startled to get a bill for $26,000 – until T-Mobile credited his account.
