With the sort-of-maybe-kind-of-partial-fix for 3G now deployed around the world, Apple may be moving on to another software patch for its seemingly problem-plagued iPhone.

An e-mail said to be from Steve Jobs indicates a new update slated for September. The update will fix a bug that causes the phones not to load some third-party apps at startup, AppleInsider reports. The site says a user had e-mailed Jobs and then received a one-line personal response:

“This is a known iPhone bug that is being fixed in the next software update in September.”

The app issue is the latest in a line of widespread problems for the iPhone, which started right off the bat with the activation day meltdown. MobileMe problems followed, and then, most recently, we’ve seen the well-reported coverage and dropped call woes.

Still, Apple is doing all right on the whole: A consumer satisfaction study made public this week shows the company scoring a record-high number, with 85 percent of its users saying they’re happy. The next highest-rated company, Dell, came in 10 percentage points lower.

Of course, that survey was probably taken before the iPhone came out. Are people still satisfied?
