Man, they’re just cranking these things out. Just two weeks after iPhone OS 3.0 Beta 3 (which was, in turn, two weeks after iPhone OS 3.0 Beta 2), we’ve got another Beta.
Beta 4 of iPhone OS 3.0 is now available for developers, as long as they’ve downloaded the brand spankin’ new iPhone 8.2 pre-release. It just went live, so we’re not quite sure what’s new here. If you spot anything, let us know – we’ll do the same.
Also, it’s starting to look like we can expect Betas every 2 weeks until release. Next one ought to be on Tuesday, May 12.
Update: Details are still incredibly sparse, but here’s what we’ve heard so far:
- MMS now working on more carriers without modified carrier bundles (Only one report – still working on confirming this.)
- General performance updates, far less crash prone than the past builds.
- The “Store” settings pane now functions, allowing you basic control over your iTunes account
- API Change: “SKErrorPaymentNowAllowed allowed and was replaced with SKErrorPaymentNotAllowed”
More as we hear it.

Store is working in Settings app.
No MMS on new build for Att&t US. The option is completely gone from the settings menu.
I am on ATT in the US and MMS is working for me now. First MMS I sent out took about 1 minute to send and another minute to receive. Second MMS sent took around 4 minutes to send and about a minute to receive. Both sent MMS’s were received twice for some reason.
