I was cheered when I heard “Well the iPhone 4G release date will be this late June and the pre-orders of iPhone 4G will be starting this June 15.” LOL. But I am a little worried about whether my iPhone 3G apps work well on the new version, here is my apps list on my iPhone now:

Shazam - a free music application tells you what songs you’re listening to, what artist sings it, and where to buy it.
Winx DVD to iPhone Ripper - convert the DVD content to iPhone.
Google App for the iPhone - I use this to search my phone for items such as Contacts, Applications, etc.
eReader - I use it to download ebooks directly to my iPhone.
WeatherBug - offers sooooo many worldwide locations whether. Totally satisfy even the most traveled users.

Just can’t wait the release date. Hope they will work well on this new version and I would not waste my time changing them, Good luck to me~
