Will Iphone 6 gonna be a mega hit? Worth to buy an iphone 5s when IP6 comes out?

Hey friends… Do you think that the iphone 6 is going to be a mega hit? Coz u all know the "s" series of iphones are an ultimate hit… And iphone 5 was an utter flop device which was discontinued within 11 months… Seriously made many buyers sad though it gets software updates in future… And a important question is can i depend upon IP6 or buy an IP5s… Coz 5s is future proof and yes rumors say that IP6 is way bigger and powerful… What should i do? Kindly help me and for a regular user IP5s is way better and i feel like IP6 has flaws as its the first try for apple with new features like screen and nfc, etc… Kindly help me guys! And sure dat IP5s will be sure cheaper when IP6 comes? And would not be discontinued?

Added (1). For your reference… Is it worth to buy an Iphone 6 on its release day itself or should i wait for few more months to know about it drawbacks and leaps and other buyer's reviews? I feel like i should not waste my hard earned money for a smartphone which has loop holes… So should stick with buying an iphone 5s on iphone 6 release as it becomes cheaper?!

IMessages not being delivered?

I'm texting my friend from iMessages, they have an iPhone, and my text doesn't say delivered and I sent it a day ago, I see my friend liking pictures and communicating on social networks, but haven't gotten a reply to my text. How can I get the message to be delivered if obviously both of us have service and phones that work?

Super Glue stuck in iPhone screw

So I was about to replace the digitizer to my phone because of an unresponsive screen and I start unscrewing the first screws at the bottom of the phone and find out one of my screws was stripped! I have never even touched the screws, but I'm assuming when I tried to sell my iphone with uSell.com that the technicians there did and I tried the super glue trick to unscrew the screw but all I got was super glue stuck in the screw… How do I get that out?!
