Do you prefer your calendar/reminders/notepad to be digital or on paper?

I'm currently debating with myself whether I should get a nice moleskine day planner and just write all my calendar events and reminders on paper, or whether I should buy an iphone to go along with my Macbook so that all my calendar events etc will be synced together over the cloud (I currently have an android phone which is pretty incompatible with Mac/Apple). Everything seems to have pros and cons and I can't make up my mind.

What do you prefer and why?

How to print photos off of PoGo instant printer using PC?

No matter how many times I try I can't print photos from my Polaroid PoGo Instant Mobile Printer, I've got an iphone so printing from there's impossible unless I jailbreak it, and sadly I don't have a digital camera except for a camcorder and a NookColor which didn't work either.

I've tried all the help pages about printing from a computer however nothing works! My PC does recognize the PoGo as a Bluetooth printer but when I click print on a photo it will not pull it up in the printers! Am considering getting a USB to USB cable, not sure if it would work, any suggestions WIDELY APPRECIATED!

Why is mobile sending number different to my number?

I recently bought an Iphone and did a sim swap so I could keep my phone number. Everything has been ok. However, when I send an imessage it shows the recipient a different number to mine. I don't think this happens when I send a SMS. Presumably it's the original number for the new sim? Why is this?

Why are the pictures on my iPhone blurry?

They've never been before, and they are really blurry. Like all of them…

Added (1). I didn't get it wet… It's 102 were I'm. Could the heat be the issue because I'm outside, but it's not in my bra or anything…

He is ignoring me? Is he or isn't he?

I met this guy online last week, don't judge or say its unsafe. I was on omegle just to talk to someone because I was bored & he came across for the same reason. We got talking like we knew each other as friends, usually I never find people I can just talk to on omegle & I gave him my number which I NEVER give out. We've been texting for over a week, except once last week since he got his phone taken away. He's been texting first most of the time literally before I'm about to text him. From what I know he's a really sweet & down to earth guy. On Wednesday we were having a normal conversation & he never replied back to the last text i sent. So I texted him hey on Thursday & he didn't reply & he usually does. He doesn't seem like the one to just stop talking like other people I know. He always apologizes when he doesn't reply soon & says goodbye when he has to go. Do you think he got his phone taken away again? We're both 17. We snapchatted once or twice (he doesn't have an iPhone, he used a relatives phone to snapchat) & he is who he says he is. I'm kind of falling for him because he's not a pig or douche bag. He's also only 5 & a half hours away. I know I'm over reacting since its only been 2 days but this has happened to me before with someone I know, they just stop talking out of no where. So is he ignoring me? He seemed to be a flirt & into the conversation & if he usually texts first, why would he ignore me?

I haven't received a 6 digit code from WhatsApp?

From some reason my iPhone had rebooted and so did WhatsApp. When I gave it my number I had not received a text from them telling me the code that is needed. I've checked everything, I've been trying this for three hours and with no result. The text won't be delivered to me.

How can an iPhone 5 under contract be activated?

I recently lost my Verizon iPhone 5, so naturally, I replaced it. However, I happened to come across it some time later, and ended up selling it to someone. They recently contacted me saying that they called Apple and can't activate it because it's under contract. What can I do to help them? They didn't give the details, but could they be trying to activate it with a different carrier's SIM card? If that IS the issue, how can they get around it? I don't want to be responsible for selling someone a phone that they can't use.

My Instagram won't let me follow or unfollow people?

I've restarted my phone twice. It's an iPhone 4S for the past week everytime I press follow it will say following, but if i revisit the page is still has the blue follow button.
