For what it's worth, "word" is the new iphone (if there is a new iphone coming) is going to be a bit bigger so your case might work on that one when you upgrade (if any of the rumors are true) so having a case that fits more than 1 size is good.
That said, and I don't want to be throwing cold water on you, but I've learned not to buy the fancier cases for my techo stuff--it changes too much (heck, I get a new cell phone every 2 years). I spent $40 on a Kate Spade iphone case and I knew that was too much, but it was too too cute. But your BV case does look nice and if your phone can't slip out, I would think that's ok because is is protecting your phone, which is the reason for these cases.
Your absolutely right, I think I am just over-thinking and as long as it stays in the case and keeps my phone safe then it has served its purpose.
If the rumor is true about the new iPhone being bigger, then I couldn't be happier
Thanks for your comment! It made me feel a lot better about it.
For anyone else who's wondering, I just confirmed with the sales at a boutique as well as their customer service representative that all iPhone cases come in ONE size. They do have identical blackberry cases which are slightly shorter in length.
