You've got a new iPhone and you're a bit blue because apparently you've been holding phones wrong your whole life. No need to buy an expensive case to fix your phone-holding habits and weak-signal woes. Fix it with a cheap bracelet.
The iPhone 4 has reception issues wherein if you hold the phone low and with your hand wrapped around the bottom half of the phone you get terrible reception. Many people hold their phone in such a fashion. If you've got a new iPhone and you've noticed your reception seems pretty awful you can either change the way you hold the phone — easier said than done! — or you can take a simple and cheap bracelet and stretch it around your iPhone as a lightweight "case" to resolve your reception issues.
The bracelets in question are the silicone-like charity bracelets that have been popular over the last few years, made most famous by the Lance Armstrong "Live Strong" campaign and their bright yellow bands. You can get them from vending machines or just keep an eye out during your daily travels where they are readily available at checkout counters in support of various charities. Check out the link below to see how one inventive iPhone owner modified his $US1 bracelet to uncover the charging port and buttons. Thanks gre9del!
