The release of the latest version of Apple’s iPhone and iPad software didn’t run as smoothly as planned. Many users reported problems when trying to download the new OS, with Apple’s servers apparently unable to keep up with demand.

   Microsoft and Google both unveiled new looks and features for their search engines. Bing's new logo echoes the fresh look Microsoft rolled out for Windows and Office, and its search results pages have been redesigned. Its new features include "pole position”, a reference box that pops up at the top of results with answers to queries, so you don't need to click to a different page.

   Under plans announced by Transport Secretary Patrick McLoughlin, 70 per cent of rail users will benefit from fast mobile broadband by 2013, although there should be a noticeable improvement in the current Wi-Fi service by 2015. "Today's announcement marks the beginning of the end of poor coverage on our railways," said McLoughlin.

   Adverts appeared in the new version of the Gmail Android app. It is believed they will initially be limited to the Promotions section of the inbox, along with marketing emails, special offers and newsletters. Reports from the blog Android Police suggest that you’ll be able to save the adverts as messages or “dismiss” (delete) them.
