Apple has today released iOS 3.2.1 for the iPad, which fixes some bugs and adds some improvements. Probably the number one fix on the list is the improved Wi-Fi connectivity, which appears to have solved a problem that many iPad owners have had with weak Wi-Fi signals. Going by the latest postings on Appleâ€™s iPad support board, the update seems to have solved those problems for many people, although one person said that installing the update had totally bricked his iPad, which is a bit worrying, as is the fact that ZDNet writer Adrian Kingsley-Hughes also said that installing iOS 3.2.1 â€œhosedâ€ his iPad. Should your iPad remain intact after the update, youâ€™ll also find that Bing has been added as a new search option in Safari. Other fixes include repairing an issue that could possibly prevent copy and paste of single-page PDF attachments in Mail, and addressing another bug that could cause video playback to freeze.
