Jonathan S. Geller who runsBGRhrd frommultiple sources that is planning to relse iOS 7 Beta 4 today at around1pm EDT / 10am PDT, over the air and through Dev Center.For what it’s worth,BGR recently nailedthe iOS 7 Beta 3 relse date.The upcoming build for an AT&T iPhone 5 should be hostedhere(the Verizon download ishere).More purported download links can be found in thisMacRumors forum post.The well-informed Mark Gurman of9to5Macsays the purported build of iOS 7 Beta 4 is ’11a4435d’, adding:I hrd last week that is nring an initial “GM1″ candidate internally. This candidate is said to be at a zero-priority-1 bug status, which mns that there are no critical bugs left in the operating system.Of course, will likely discover more bugs in its testing, and will likely have several internal GM candidates before relsing the final GM seed to developers later in the yr.BGR was told thatthe fourth beta should contain“more bug fixes, graphics and UI enhancements and a couple of other updates”.Some non-developers who installed iOS 7 Betas took to Twitter to complain about the operating system’s sluggishness and a huge hit on battery,not rlizingbeta is normallyoptimized for battery and graphics performance either in a Gold Master candidate or the beta preceding it.With that in mind, we’re expecting the fifth or sixth beta to be optimized for battery-friendly, jerk-free performance.
