Dear Jose - I don't see any reason why I should complain about the iPhone - it works great and I love it.
Just remember:
There's currently no "cut and paste", nor "copy and paste" available. -And, alas, it looks like that capability is low on Apple's "iPhone To-Do" list for now.
There are a couple of Apps that allow you to use the "landscape keyboard" for your Mail replies. However, there are still no Apps for using the "landscape keyboard" for text messages.
*I still love my iPhone (too), and unlike some of my friends, I've been very "lucky" with the standard features and connectivity. However, it does seem that Apple has been quietly acknowledging that there are some "dud iPhones" out there...
"Oh, well, it looks like we're going to have to replace your iPhone at no cost to you."
