Well as it turns out there was a catch, according to an email that was sent out to a current MobileMe subscriber which basically outlined a couple of details about iCloud services. For starters it looks like when users sign up for a free iCloud account, they are given 5GB of storage space, as highlighted by the email.
The email also goes on to reveal that when you do reach your 5GB limit, you have the option of either deleting some of the data stored in the cloud to free up space or they can purchase additional space for a fee, which we believe is the catch behind iCloud’s “free” services. Since iCloud is Apple’s answer to a new form of storage, we’re guessing that 5GB is by no means enough to keep the entire contents of your phone, tablet, and computer which means it’s very likely users will be purchasing additional storage space. The email does not state how much users can expect to be paying for the additional space but more will be revealed as iCloud approaches its release date which is supposed to be in fall along with iOS 5.
