Huge issues on the new z10 !!!

i recently purchased a BB Z10 in Dubai (UAE) with lot of anticipation and excitement, all to realize that i wasted my money and excitement over a dumb phone !!!! Yes you read it right, dumb phone ever since day one my BB has been acting weird when trying to connect to the WiFi at my office, my home or anywhere for that matter, it does not have tools to scan the network manually and it doesnt show the network at my home which i own, rather it shows networks which are in the neighbouring areas, if at all it shows my own wifi network it would not connect , initially i thought it was my wifi which was bad, but i tried all my other devices on the same network to findout they were working perfect.

Second issue is the phonebook, at times when you are searching for a contact and open it and then exit it it would not exit out of the phone book entry the phone does not hang but the phone book does !!! you exit the phone book and open again and it shows the same spot where you left...... this has happned more then 10 times, i had to swipe my data 3 times and reset the whole data to get a solution, but in vain.

One of my friend in India purchased a Z10 too and when he was set to use he got a upgrade notification, the moment he upgraded the phone his phone went dead, he then had to re-install the whole os from some service centre to use the phone yet he has issues far from being solved.

BIS/BLACKBERRY are you really running towards your end ???? Can someone help me out solving the wifi and phone book issues ????

thanks in advance
