Clicking the purported download link, available here, returns a 'Your session has expired' error page. Other URLs with similar build numbers, on the other hand, return an 'Access Denied' error message.
Apple is expected to release Beta 4 later today.
BGR has some additional iOS 7 beta-related claims as well:
Additionally, one source has informed us that the company plans to release just two more betas for developers before the gold master (GM) version is released in early September.9to5Mac somewhat corroborates this, claiming that Apple is nearing "zero-priority-1 bug status", meaning there are no critical bugs left in the OS and the company is getting close to releasing a "GM1" candidate internally. Apple typically releases several internal GM candidates before releasing a final GM seed to developers for testing.
