Notorious hacker group Lulzsec finished off their string of fifty high-profile server hacks yesterday with a bang: they released some AT&T internal documents that reveals that AT&T have already tested the iPad running on their next-gen 4G LTE network.

Wondering what’s changed in the latest developer preview of iOS 5? Although there’s always countless tweaks to be found in every beta of a major new iOS release, here are twelve of the bigger changes that have caught our eye so far.

It’s been a great week for iOS gamers, with fantastic new releases from Gameloft, Chillingo, Sega and Telltale Games. Picking our favorites has been some task.

Here’s this week’s roundup — featuring the return of Sonic in a brand new arcade kart racer, an iPad platformer that uses your iPhone as a controller, and the final episode of Monkey Island.

We come to the last week of June with three hardware deals: two max-out iMacs and a number of MacBook Air laptops. First up is an iMac desktop sporting an Intel Core i7 quad 2.93GHz engine. The iMac with a 27-inch screen is also bundled with a 2TB hard disk drive for just $1,828. Next is an iMac with an Intel Core i3 dual 3.2GHz processor. The iMac with a 27-inch screen is bundled with 8GB of RAM and a 3-year AppleCare plan – all for just $1,519. Finally, if you’re looking for a more light-weight mobile option, check out a number of MacBook Air units, starting with a 1.4GHz model with 64GB SSD and 2GB of RAM for just $829.

Along the way, we also check out a number of other Apple-related items, including a bike mount for your iPhone, a 72 percent discount on select tablet accessories, and other gadgets for your iPhone, iPad or Mac. As always, details on these and many others can be found at CoM’s “Daily Deals” page starting right after the jump.

It’s a total embarrassment, but less than a year after Microsoft finally “caught up” with Apple’s three year lead and released a modern, multitouch smartphone operating system in Windows Phone 7, Microsoft is having to do it again, this time having been caught with their pants down by the iPad.

Their solution? Windows 8, the next version of their desktop operating system, carefully optimized to support power-sipping ARM processors and skinned with a special, tablet-specific operating system. Now a report suggests that Microsoft will rush Windows 8 to market to make sure that the iPad 3 doesn’t eat Microsoft’s tablet lunch before they’ve even sat down to the table.

Remember Marathon? If you’re a long-time Mac user, sure you do: back in the early 90s, Bungie’s sci-fi FPS series was the one shining light illuminating the Steveless Dark Ages of Macintosh gaming. Even if you’re only a recent convert to Mac, though, you’re probably familiar in a roundabout way with Marathon: it takes place in the same universe and is the direct prequel to Bungie’s bestsellingHalo series for the Xbox 360.

Either way, we’ve got great news for any Apple gamer. Marathon’s coming back… this time for the iPad.

Here’s a little gem I found on the App Store this week. +Loop is a video recorder app for iDevices, but it stands out from the crowd because it records multiple mini video clips in one, and costs nothing.

This is Monster Soup, my latest favorite puzzle for iOS. It’s a fast-paced color-matching game with lots of personality and a great sense of humor.

BestBuy.com — a major Apple reseller — has now stopped shipping the current-generation of Apple’s ultraportable notebook as an upcoming refresh becomes ever more apparent.

This week’s roundup of must-have applications features one of the most unique video apps we’ve ever seen for the iPhone, a fantastic new note-taking app from tablet-maker Wacom, and a simplistic calendar app that aims to bring old-school desktop calendars to your iPhone.
