I've been an Android user for many years, and pre-ordered the 6s 64GB. Since I've been with Android for years, all my services are tied with Google such as contacts, calendar, email, Google Voice w/ Hangouts, etc. What should I expect when moving to iOS this Friday? I do love being able to use Google services as their web-based calendar and contacts are great. Can I continue to use them and sync my contacts and calendar with my new iPhone? I remember reading something about setting up a CalDev account. I also use Google Voice with hangouts and not my carrier number for SMS and calls, but I plan to move that back, but will I be able to receive calls and texts by downloading Hangouts on iOS? I'm really just looking for what I should expect when I get my new iPhone, and if there are any major issues I'll run into. Thanks!
