Yahoo! has reportedly fixed an IMAP bug that caused the iPhone and Windows Phone devices to transmit loads of superfluous data over 3G. The bug worked like this: when a user went to check their email, the server would send more information to a user’s phone than was required to just check mail. This resulted in people accidentally consuming loads of rouge data each month. Microsoft first responded to the issue back in January after Windows Phone users began complaining about alerts stating that they were nearing their monthly data cap. On February 1st, Microsoft said that it had determined that the bug was caused by an inefficiency in the Yahoo! Mail email client and that the problem would be fixed in an upcoming update. Just two days later, programmer Rafael Rivera took the situation into his own hands, and during his investigation, discovered that the bug wasn’t just confined to Windows Phone 7 devices — it was also present on the iPhone. Just recently, Rivera updated his blog noting that Yahoo had fixed the issue and has upgraded its software from version 0.7.65_12.286037 to version 0.7.65_14.298026.
