With the most recent release this month, the wait for the next iPhone may be at least a year. Historically, that is the least amount of time between releases: June 2007 (original), July, 2008 (3G), June 2009 (3GS), June 2010 (4) and finally October 2011 (4GS). With the iPhone 4 staying one of the most popular smartphones even a year after its release, I don't see Apple releasing a new phone until they have something new to offer. As to whether there will ever be a larger screen, there are a lot of well connected and intelligent people who think that is what the iPad is for. -- Suzanne
