In a note to clients — as reported by “AppleInsider” ( — Sterne Agree analyst said his sources indicate that the upcoming iPhone 5 could be a more significant upgrade than previous rumors have suggested, sporting a larger display and thinner design.

He thinks the fifth generation iPhone will feature a slightly larger display than the current 3.5-inch screen found on the iPhone 4. It’s also expected to feature the same dual-core A5 processor already found in the iPad 2.

In addition, Agree says the new iPhone will feature a similar form factor and size to the iPhone 4, but will sport a thinner bezel. However, it’s not expected to have 4G-LTE high-speed wireless data connectivity. The new technology still has issues with battery life and network coverage, problems that Wu believes Apple will fix at some point in the future.
