iPad 2 supply constraints improved, next iPhone orders arriving 'several months later than usual'

According to AppleInsider, Shaw Wu with Sterne Agee issued a research note today stating that iPad 2 constraints have "significantly improved" this quarter thanks to "retooling and conversion of more overseas production lines." That's good news for those of you still waiting to get your hands on an iPad 2.

A second report out today from Piper Jaffray analyst Gene Munster says that Apple's orders for new iPhone parts are "several months later than usual." Munster sees the delayed parts order as a sign that the rumors saying the next iPhone won't ship until September are correct. Munster has also assembled a chart indicating that there are, on average, 79 days between an iOS software event and the iPhone hardware announcement and 99 days between the iOS software event and the actual ship date of the new iPhone. According to those averages, based on the likelihood of iOS 5 being revealed on June 6 (at WWDC), the fifth-generation iPhone will be announced on August 24 and ship on September 13.
